Which type of 2 stroke oil?

[THEFERMANATOR]

Pre-mix or injected? I personally run PENNSOIL synthetic blend in mine, but WAL-MART is discontinuing sales of it and is switching over to the QUIKSILVER stuff. QUIKSILVER is just an okay oil that I feel is VERY over rated for what it costs. EVINRUDE XD-30 or 50 is also a good oil that is said to work very well as well, but is a little more costly to buy(unless you buy it in bulk). YAMALUBE is also a decent oil, but I never bought into the hype behind it as I always had plug fouling issues with it.
